There are 3 selections of the two nylon inserts. White is the least cost and can be dyed a color, Gray is close to the aluminum color, and Black is best for blocking UV.
Made for Beneteau 235 with a Z190 mast that has two feed slots of different cutout measurements.
Top slot = 44mm x 11mm (insert has one bottom nipple tab)
Bottom slot = 75mm x 17.3mm (insert has side barbs & one bottom nipple tab)
All nipples have a 1/16" drill guide hole to mark the location in the feed slot to drill a 3/16" hole into the back web.
The nipple pin will drop into the hole to prevent the insert from sliding out of position when sail slugs run through it.
